 == Sorting Trees ==
 The <tt>TreeCollection</tt> class keeps trees sorted in the current period. This makes it easy and fast to iterate over trees with a certain state, since all those trees are kept together.
 == Adding new Trees ==
 Both the ingrowth model and the regeneration models creates and adds new <tt>Tree</tt>s to a <tt>PredictionUnit</tt>.
